Helper scripts

FAI-Tools

Jan Jansen sent me an interesting tool that should help with management of the FAI configdir get the file

his mail:

Hi,
As long as there were no responses to this posting, i don't dealed with
this idea (GPL) but if some user would find it usefull that would be
also nice for me because i don't have that much time anymore now to fix
all known (and probably unknown) bugs alone. A problem could also be the
currently, only with shell-options available, documentation.
So i post some hints here:
- if a file doc/<class> exists in your fairep, it will be shown as
class-description in info mode
- new script styles ([0-9][0-9]-*) can cause little errors
- some extravagant string values can cause qouting errors (shell
problem)
- create mode not fully funtional

Installation:
Unzip the archive to a directory and adjust the lib and tmp paths in
file 'ftool' to the right place. Now the script should be funtional.
Keep attention to test it the first times with a copy of your repository
to not destroy your classes/files in case of missusing or unexpected
errors (which hopefully aren't that much).

failint.sh a lint checker for FAI. (detects common mistakes)

FAI development and testing helpers

I created some scripts that help setting up a FAI developemnt environment, and running builds and tests in there. At the moment it's mostly about creating fai-cd's and testing them in a qemu vm. Eventually I will add functions for network installation testing with a real hardware host and a qemu client, as well as testing network install with a qemu hist and a qemu client. I am quite interested if someboy finds them useful, they are in subversion:

fast fai-cd creation script

when developing a new fai-cd it can happen that you need to create new fai-cd's very often. It gets annoying that you always need to delete fai-mirror and the old image... unless you use a script like this (change your tmp path for image and mirror):

#!/bin/sh

FAI_MIRROR_LOCATION=/data/produktion/tmp/fai-mirror

DATE=`date +%Y-%m-%d_%h-%M-%S`

if [ -z $1 ];then
  CDIMAGE=/data/produktion/tmp/fai-cd_${DATE}.iso
  echo "using default cdimage location $CDIMAGE"
else
  CDIMAGE=$1
fi

if [ -z $FAI_MIRROR_LOCATION ]; then
  echo "error - FAI_MIRROR_LOCATION is empty - exiting"
  exit 1
else
  echo "cleaning up fai-mirror at $FAI_MIRROR_LOCATION"
  rm -r $FAI_MIRROR_LOCATION
fi


mkdir -p $FAI_MIRROR_LOCATION

fai-mirror -a $FAI_MIRROR_LOCATION

CDIMAGE_BACKUP=${CDIMAGE}_bak_date +%Y-%m-%d_%h-%M-%S

if [ -f $CDIMAGE ];then
  echo "moving old cd image to $CDIMAGE_BACKUP"
fi

fai-cd -m $FAI_MIRROR_LOCATION $CDIMAGE

turn kernel bootprompt parameters into classes

Every kernel parameter after the -- separator is changed to uppercase and used as a classname.

class/35-bootprompt :

#!/usr/bin/perl
use strict;
use warnings;

my $separator = '--';

my $seen;
foreach ( split /\s+/, `cat /proc/cmdline` )
{
  if ( $_ eq $separator )
  {
    $seen = 1;
    next;
  }
  next unless $seen;
  print uc
    if m/^\w+$/;
}
